A student of the sociological direction Slava can not choose a topic for a graduation project in any way. The thesis supervisor recommends reading one little-known old book. Slava agrees and does not even suspect that his attempts to find the book will turn into a real treasure-hunting adventure.

Senior Lieutenant of the Navy Aleksey Alekhin, once descending to the seabed in a bathyscaphe, finds himself in a strange underwater cave that serves as a portal to a fabulous world. In this new unfamiliar place, he meets a little dragon left without a mother. Aleksey unwittingly becomes the dragon's guardian and friend and gives the baby the name Gorynych.
